I recently bought an Eclipse done 66000 Miles. In the Maintenance Manual it is stated, "60000 Miles : replace timing belt. (For California, Massachusetts, Vermont and MAINE this maintenance is recommended but not required."

May anybody explain if I need to replace my timing belt. Of what is the milage to replace it?

Depends on which engine you have, and how dependent on the vehicle you are.


I have a 1993 1.8L engine, which is a "non-interference" engine - ie, if the timing belt breaks, the engine just stops, the fast moving pistons won't hit the valves that suddenly stopped moving. I can leave the car on the side of the road and walk home.



If you have an interference engine, like the early 2.0L engines in the Eclipse, you absolutely should replace the timing belt. If you don't and it breaks, you'll be replacing the timing belt, up to half of the valves, and possibly some of the pistons, as the pistons will slam into the open valves that aren't closing in time b/c the timing belt broke.



What year is your Eclipse and what size engine do you have?

Thanks for the reply. Its is 2003 GT. In maintenance book I found that it is stated on 100000 miles the timing belt to be replaced, if not replaced earlier. So is that mean that is the time to be done it?

First @60000 miles says "replace timing belt". But it is noted with a foot note that 'it is recommended for California and a few states but not required.' Again @100000 miles, it is said that "replace timing belt if not replaced earlier.

Yes it is a V6 engine.

Bouncing between Wikipedia and various forums, it appears the 24 valve 6G72 engine is an interference engine. So replace your timing belt now, and every 60,000 miles hereafter.
